In the quote from Diana Gabaldon's "Virgins," a character expresses a deep emotional connection that transcends physical presence. They remind Jamie that although he may not be able to see them, they are always thinking of him. This sentiment emphasizes the enduring bonds of family and love, even when separated by distance or time.
The reference to looking up at the stars serves to bridge the gap between them, suggesting that they share the same universe and that their thoughts and feelings are intertwined. It highlights the idea that love remains steadfast, no matter the circumstances, providing comfort and reassurance amid separation.
